Description
Technical field
The present invention relates to a kind of headrest, relate in particular to a kind of car seat headrest.
Background technology
The car seat headrest that is located at the automotive seat top generally is to play the effect of supporting occupant's head, alleviating fatigue; Main is plays the effect that protection occupant's neck is avoided damaging when crashing; But the car seat headrest that generally uses at present can only carry out up-down adjustment according to the position of occupant's head, and can't level move forward, like this when automobile crashes; The occupant is under the effect of impulsive force; Move with car seat headrest behind the head inertia and contact, though this moment, car seat headrest played the effect of supporting to occupant's head, protection to a certain degree occupant's neck; But often owing to move behind the inertia of occupant's head, occupant's neck is produced the phenomenon of whipping injury simultaneously and car seat headrest occurs.
Chinese patent " a kind of automotive headrest (CN101331035A) " discloses a kind of car seat headrest; Said automotive headrest comprises having the strut that is used for fixing the vertical component effect on the seat; And with the interconnective horizontal part of said vertical component effect; Horizontal guide frame is fixed in the horizontal part of said strut, and ratchet slider is movably mounted in said horizontal guide frame, and the ratchet pawl locking perhaps discharges said ratchet slider; Extension spring makes the ratchet slider after moving return its initial position, and the ratchet spring is that said ratchet pawl provides pulling force.Though this car seat headrest can move forward the headrest level according to occupant's needs; But this apparatus structure is complicated; And can't be according to the needs of emergency case; Automatically with chair headrest reach fast in time, whipped injury when especially automobile collision accident taking place to avoid occupant's neck, thus more effective protection occupant.
Summary of the invention
The present invention has overcome car seat headrest apparatus structure complicacy in the prior art; Can't be according to the needs of emergency case, in when, especially automobile collision accident taking place with chair headrest reach fast in time automatically, occur car seat headrest to occupant's neck produce whip injury shortcoming; Provide a kind of simple in structure; Be skillfully constructed, and can automatically chair headrest be in time moved forward fast when especially automobile collision accident taking place according to emergency case; Avoiding occupant's neck to be whipped injury, thus a kind of car seat headrest of more effective protection occupant.
Above-mentioned technical matters of the present invention mainly is able to solve through following technical proposals: a kind of car seat headrest; Comprise and back of seat bonded assembly headrest bracing frame and the chair headrest of being located at headrest bracing frame front side; It is characterized in that; Be provided with the headrest fixed mount at the rear portion of described chair headrest, described headrest fixed mount links to each other with the headrest bracing frame through the telescoping mechanism that can stretch in the horizontal direction; On described back of seat, be provided with trigger mechanism, described telescoping mechanism links to each other with trigger mechanism.Through rear portion the headrest fixed mount is set, can plays effect fixing and the support headrest at chair headrest; But, can realize chair headrest reach or withdrawal through at the flexible telescoping mechanism of setting along continuous straight runs between fixed mount and the headrest bracing frame of resting the head on; Through trigger mechanism is set on back of seat, when automobile bumps, because occupant's back inertia moves the trigger mechanism on the touching back of seat backward; Trigger thus and start the telescoping mechanism that is attached thereto; Make chair headrest realize automatically reach fast, reach and avoid occupant's neck to be whipped injury, actv. protection occupant's purpose; Simple in structure, be skillfully constructed.
As preferably; Described telescoping mechanism comprises the master arm and the slave arm of two pairs of cross-articulation that are symmetrically distributed in the chair headrest both sides; Hinged respectively active sliding block and the active fixed block of being provided with at the two ends of described master arm; Hinged respectively driven sliding block and the driven fixed block of being provided with in the two ends of slave arm; The active fixed block of described master arm one end is fixed in the bottom of the vertical supporting bar of headrest bracing frame; The active sliding block of the other end slidably is located on the top of vertical fixed link of headrest fixed mount, and the driven fixed block of described slave arm one end is fixed in the bottom of vertical fixed link of headrest fixed mount, and the driven sliding block of the other end slidably is located on the top of the vertical supporting bar of headrest bracing frame; Between the driven sliding block of described chair headrest and arranged on left and right sides, be provided with the sliding block joint bar, described driven sliding block links to each other with trigger mechanism through detent mechanism.Through the master arm and the slave arm of two pairs of cross-articulation, and at the two ends of master arm and slave arm hinged slide block and the fixed block of being provided with, can realize the reach of coupled chair headrest or regain, simple and reliable for structure; Distribute in the chair headrest bilateral symmetry through two pairs of master arms and slave arm, guarantee the telescopic process of chair headrest and support steadily reliable; Through between the driven sliding block of chair headrest and arranged on left and right sides, being provided with the sliding block joint bar; Guarantee that chair headrest left and right side in telescopic process keeps synchronously; Be the stability that improves the chair headrest telescopic process so on the one hand; Prevent that consequent one-sided wearing and tearing from reducing the service life of chair headrest, can guarantee the stability when the chair headrest reach is implemented protection to occupant's neck on the other hand, prevent the damage that the chair headrest deflection possibly brought the occupant.
As more preferably; Between the active fixed block of described chair headrest and arranged on left and right sides, be provided with fixed connecting rod; Between described sliding block joint bar and fixed connecting rod, be provided with spring, the middle part that is hung on sliding block joint bar and fixed connecting rod is blocked at the two ends of described spring respectively.Through between the active fixed block of both sides, fixed connecting rod being set, improve the intensity of headrest bracing frame; Through between sliding block joint bar and fixed connecting rod, spring being set, after being triggered, chair headrest can quicken the chair headrest reach according to the recovery elastic force of spring, and guarantee that chair headrest in time moves forward to implement protection, thereby guaranteed that chair headrest implements the validity of protection.
